# PetscCuBLASIntCast
like `PetscBLASIntCast()`, but for `PetscCuBLASInt`. 
## Synopsis
```
static inline PetscErrorCode PetscCuBLASIntCast(PetscInt a, PetscCuBLASInt *b)
```
Not Collective


## Input Parameter

- ***a -*** the `PetscInt` value



## Output Parameter

- ***b -*** the resulting `PetscCuBLASInt` value





## Notes
Errors if the integer is negative since PETSc calls to cuBLAS and friends never need to cast negative integer inputs


## See Also
